Extended details and known issues

Additional detail and explanation of the esoteric parts of normalize.css.

pre, code, kbd, samp

The font-family: monospace, monospace hack fixes the inheritance and scaling
of font-size for preformatted text. The duplication of monospace is
intentional. Source.

sub, sup

Normally, using sub or sup affects the line-box height of text in all
browsers. Source.

select

By default, Chrome on OS X and Safari on OS X allow very limited styling of
select, unless a border property is set. The default font weight on optgroup
elements cannot safely be changed in Chrome on OSX and Safari on OS X.

[type="checkbox"]

It is recommended that you do not style checkbox and radio inputs as Firefox's
implementation does not respect box-sizing, padding, or width.

[type="number"]

Certain font size values applied to number inputs cause the cursor style of the
decrement button to change from default to text.

[type="search"]

The search input is not fully stylable by default. In Chrome and Safari on
OSX/iOS you can't control font, padding, border, or background. In
Chrome and Safari on Windows you can't control border properly. It will apply
border-width but will only show a border color (which cannot be controlled)
for the outer 1px of that border. Applying -webkit-appearance: textfield
addresses these issues without removing the benefits of search inputs (e.g.
showing past searches).
